I found a site which gave me free a free xbox live code for 2 months and i wanted to share so here it is:
mspointsnowfree.tk
This site DOES NOT ask for CC, signup for any site, xbox account details, or anything like that. THIS SITE ONLY ASKS FOR NAME AND EMAIL and they email the code to you. I got my code after 2 days because there are alot of people getting codes. Also I tried multiple codes but i only got one for each ip, so you can't try getting hundreds of codes. Check out the site and get your code before they run out:
